FIG. 2 is a schematic block diagram illustrating an electronic device according to various exemplary embodiments.

Referring to FIG. 2, the electronic device 201 (e.g., the electronic device 101 of FIG. 1) may include a plurality of antennas. For example, the plurality of antennas may be included within a housing of the electronic device 201.

The electronic device 201 may transmit and receive data to or from a network 29 using at least one of the plurality of antennas.

The electronic device 201 may transmit a signal corresponding to data to the network 298 using at least one of the plurality of antennas.

The plurality of antennas may include a first antenna and a second antenna. For example, the first antenna may be located in a lower end portion 285 of the electronic device 201 (or the housing of the electronic device 201), and the second antenna may be located in an upper end portion 295 of the electronic device 201 (or the housing of the electronic device 201).

The performance of the antennas included in the electronic device 201 may deteriorate depending on external factors or internal factors. For example, when a user holds the electronic device 201, the performance of the first antenna located in the lower end portion 285 of the electronic device 201 may deteriorate.

According to various exemplary embodiments, when the performance of the first antenna is lower than a specified performance level, the electronic device 201 may transmit a signal, which is transmitted to the network 298 via the first antenna, to the network 298 via the second antenna. That is, the electronic device 201 may transmit the signal to the network 298 through the second antenna which has less performance deterioration.

Therefore, when the performance of the first antenna disposed in one area (e.g., the lower end portion 285) of the electronic device 201 deteriorates, the electronic device 201 may switch a path for a signal to the second antenna disposed in another area (e.g., the upper end portion 295) of the electronic device 201, thereby minimizing the loss of the signal transmitted to the network 298.

The electronic device 201 may transmit a signal corresponding to data to the network 298 using the plurality of antennas in order to improve the throughput of an uplink for transmitting data to the network 298. For example, the electronic device 201 may transmit a plurality of signals with a plurality of frequency bands corresponding to a plurality of different data to the network 298. For example, the electronic device 201 may provide uplink carrier aggregation by using the plurality of antennas connected to a plurality of ports.

The network 298 (e.g., the network 198 of FIG. 1) may transmit and receive data to and from the electronic device 201.

The network 298 may specify a frequency band (e.g., a low-frequency band, a medium-frequency band, or a high-frequency band) for a transmission signal relating to data transmitted by the electronic device 201. For example, the electronic device 201 may convert data to be transmitted into a signal in a frequency band specified by the network 298 according to the frequency band and may transmit the converted signal to the network 298.

The network 298 may provide uplink carrier aggregation. The electronic device 201 may convert first data and second data to be transmitted into signals (e.g., a Primary Component Carrier (PCC) and a Secondary Component Carrier (SCC)) corresponding to frequency bands (e.g., a low-frequency band, a medium-frequency band, and/or high-frequency band) specified by the network 298 according to the frequency bands and may transmit the converted signals to the network 298.

For example, the processor 220 may monitor the performances of the first antenna 280 and the second antenna 290 in real time or periodically, and may compare the performances of the first antenna 280 and the second antenna 290. Alternatively, when it is detected that an electronic device (the electronic device 201 of FIG. 2) is held by a user (or user's body part) (or when deterioration of an antenna (e.g., the first antenna 280) is detected), the processor 220 may compare the performances of the first antenna 280 and the second antenna 290.

The processor 220 may compare the performance value 913 of the first antenna 280 with the performance value 912 of the second antenna 290. For example, since the performance value 912 of the second antenna 290 is higher than the performance value 913 of the first antenna 280, the processor 220 may determine that the second antenna 290 has better performance.

The processor 220 may determine whether switching between the first antenna 280 and the second antenna 290 is required on the basis of the difference 914 between the performance values of the first antenna 280 and the second antenna 290 for the second frequency band. For example, when the difference 914 between the performance values of the first antenna 280 and the second antenna 290 is a specified value or greater, the processor 220 may determine that switching between the first antenna 280 and the second antenna 290 is required. Specifically, when a difference in performance value corresponding to a 6 dB noise occurs, the processor 220 may determine that switching between the first antenna 280 and the second antenna 290 is required.

For example, when switching occurs from the first antenna 280 to the second antenna 290 for the first frequency band, an improvement in performance value of 1.4 (WHP TRP) may be achieved with a conduction value of 23.5, an improvement in performance value of 0.7 (WHP TRP) may be achieved with a conduction value of 23.7, and an improvement in performance value of 2.4 (WHP TRP) may be achieved with a conduction value of 23.6.

When switching occurs from the first antenna 280 to the second antenna 290 for the second frequency band, an improvement in performance value of 2.3 (WHP TRP) may be achieved with a conduction value of 23.5, an improvement in performance value of 1.3 (WHP TRP) may be achieved with a conduction value of 23.8, and an improvement in performance value of 0.8 (WHP TRP) may be achieved with a conduction value of 23.7.

Accordingly, when the performance of the first antenna 280 provided in one area of the electronic device 201 deteriorates, the processor 220 may switch a path for a signal to the second antenna 290 provided in another area of the electronic device 201, thereby reducing the loss of a signal transmitted to a network 298.

FIG. 10 is a flowchart illustrating the antenna switching operation of an electronic device according to various exemplary embodiments.

Referring to FIG. 10, in operation 1001, a processor (the processor 220 of FIG. 3A) may transmit data (DATA) to a network 298 via a second antenna 290 according to the antenna switching operation.

In operation 1003, the processor 220 may compare the performance of a first antenna 280 and the performance of the second antenna 290. For example, the processor 220 may monitor the performances of the first antenna 280 and the second antenna 290 in real time or periodically and may compare the performances of the first antenna 280 and the second antenna 290.

When the performance of the first antenna 280 is better than (or is equal to) the performance of the second antenna 290 (Yes in operation 1005), the processor 220 may switch the antenna for transmitting the data (DATA) to the network 298 from the second antenna 290 to the first antenna 280 in operation 1007. Further, the processor 220 may transmit the data (DATA) to the network 298 via the first antenna 280 in operation 1007.

When the performance of the first antenna 280 is not better than (or is not equal to) the performance of the second antenna 290 (No in operation 1005), the processor 220 may transmit the data (DATA) to the network through the second antenna 290 in operation 1009.

FIG. 11 is a flowchart illustrating the antenna switching operation of an electronic device according to various exemplary embodiments.

Referring to FIG. 11, in operation 1101, a processor (the processor 220 of FIG. 3A) may transmit data (DATA) to a network 298 via a first antenna 280.

In operation 1103, when performance deterioration of the first antenna 280 is detected, the processor 220 may determine that antenna switching is required. For example, the processor 220 may switch the antenna for transmitting the data (DATA) to the network 298 from the first antenna 280 to a second antenna 290.

The processor 220 may verify the frequency band of the data (DATA). For example, when the frequency band of the data (DATA) is a low-frequency band, the processor 220 may immediately connect a first port 231 to the second antenna 290 through a first switch 257. The processor 220 may output the data (DATA) from the first port 231 to the second antenna 290, thereby transmitting the data (DATA) to the network 298 via the second antenna 290.

When the frequency band of the data (DATA) is not a low-frequency band, the processor 220 may determine the time to switch from the first antenna 280 to the second antenna 290 in operation 1105.

In operation 1107, the processor 220 may determine whether there is data to be transmitted to the network 298 in a first transfer time interval (TTI) (or current TTI) corresponding to a current time and a second TTI (or next TTI following the current TTI) corresponding to the next time following the current time. For example, the current time may refer to a TTI corresponding to the current time, and the next time may refer to a TTI following the current TTI. That is, the processor 220 may determine whether data to be transmitted to the network 298 is assigned for the first TTI and the second TTI following the first TTI.

When there is data to be transmitted to the network 298 in the current time (e.g., the first TTI) and the next time (e.g., the second TTI following the first TTI) (Yes in operation 1107), the processor 220 may wait until there is no data to be transmitted to the network 298 in the current time (e.g., the first TTI) and the next time (e.g., the second TTI).

When there is no data to be transmitted to the network 298 in the current time (e.g., the first TTI) and the next time (e.g., the second TTI) (No in operation 1107), the processor 220 may start antenna switching.

In operation 1109, the processor 220 may block the first path from the first port 231 to the first antenna 280 and may establish a second path from the second port 232 to the second antenna 290.

When the second path is completely established, the processor 220 may output the data (DATA) from the second port 232 to the second antenna 290 and may transmit the data (DATA) to the network 298 via the second antenna 290 in operation 1111.

FIG. 12 is a graph illustrating the antenna switching time of an electronic device according to various exemplary embodiments.

Referring to FIG. 12, when antenna switching is required, a processor 220 may determine the time to switch from a first antenna 280 to a second antenna 290.

The processor 220 may determine the time to switch from the first antenna 280 to the second antenna 290 on the basis of whether there is data to be transmitted to a network 298 in a first TTI (e.g., a current TTI) corresponding to a current time and a second TTI (e.g., a next TTI following the current TTI) corresponding to the next time following the current time. For example, it may take 2 ms to 3 ms to switch from the first antenna 280 to the second antenna 290.

The processor 220 may determine whether data to be transmitted to the network 298 exists (or is assigned) for the current time (e.g., the first TTI or the current TTI) and the next time (e.g., the second TTI or the next TTI). For example, time allocated for the processor 220 to transmit one piece of data may be 1 ms.

When there is no data to be transmitted to the network 298 in the current time (e.g., the current TTI) and the next time (e.g., the next TTI), the processor 220 may start antenna switching. Further, when there is no data to be transmitted to the network 298 for a specified period of time (e.g., 2 ms), the processor 220 may start antenna switching.

When there is data to be transmitted to the network 298 in at least one of the current TTI and the next TTI, the processor 220 may wait to start antenna switching until there is no data to be transmitted to the network 298 in the current TTI and the next TTI.

For example, when antenna switching is performed without determining whether there is data to be transmitted to the network 298 in the current TTI and the next TTI, up to three pieces of data may be lost due to the antenna switching operation.

However, when antenna switching is performed on the basis of whether there is data to be transmitted to the network 298 in the current TTI and the next TTI, only up to one piece of data may be lost.

FIG. 13 is a flowchart illustrating the antenna switching operation of an electronic device according to various exemplary embodiments.

Referring to FIG. 13, in operation 1301, a processor (the processor 220 of FIG. 3A) may transmit data (DATA) to a network 298 via a first antenna 280.

In operation 1303, when performance deterioration of the first antenna 280 is detected, the processor 220 may determine that antenna switching is required. For example, the processor 220 may switch the antenna for transmitting the data (DATA) to the network 298 from the first antenna 280 to a second antenna 290.

The processor 220 may verify the frequency band of the data (DATA). For example, when the frequency band of the data (DATA) is a low-frequency band, the processor 220 may immediately connect a first port 231 to the second antenna 290 through a first switch 257. The processor 220 may output the data (DATA) from the first port 231 to the second antenna 290, thereby transmitting the data (DATA) to the network 298 via the second antenna 290.

When the frequency band of the data (DATA) is not a low-frequency band, the processor 220 may establish a second path from a second port 232 to the second antenna 290 in operation 1305.

In operation 1307, the processor 220 may determine whether the second path is completely established.

When the second path is not completely established, the processor 220 may maintain the first path from the first port 231 to the first antenna 280 until the second path is completely established in operation 1309.

When the second path is completely established, the processor 220 may block the first path from the first port 231 to the first antenna 280 in operation 1311. For example, the processor 220 may transmit the same data (DATA) to the network 298 through each of: the first antenna 280 corresponding to the first path and the second antenna 290 corresponding to the second path until the first path is blocked.

In operation 1313, the processor 220 may output the data (DATA) from the second port 232 to the second antenna 290 and may transmit the data (DATA) to the network 298 via the second antenna 290.

FIG. 14 is a graph illustrating the antenna switching time of an electronic device according to various exemplary embodiments.

Referring to FIG. 14, when antenna switching is required (or requested), a processor 220 may newly establish a second path from a second port 232 to a second antenna 290. Here, the processor 220 may maintain an existing first path for outputting data (DATA) from a first port 231 to a first antenna 280 instead of blocking the first path. That is, the processor 220 may output the data (DATA) to the first antenna 280 through the existing first path.

The processor 220 may determine whether the second path is completely established. The processor 220 may take a certain period of time (e.g., t1) to completely establish the second path.

The processor 220 may maintain the existing first path and may output the data (DATA) to the first antenna 280 through the first path until the second path is completely established.

The processor 220 may activate both the first path and the second path for a specified time (e.g., t2) even though the second path is completely established. The processor 220 may transmit the same data (DATA) to a network 298 via the first antenna 280 connected to the first path and the second antenna 290 connected to the second path for the specified time (t2). Here, the network 298 may receive two pieces of the same data (DATA) from the first antenna 280 and the second antenna 290.

When the second path is completely established (or the specified time (t2) elapses), the processor 220 may block the first path from the first port 231 to the first antenna 280. When the first path is completely blocked, the processor 220 may complete the antenna switching operation.

When the antenna switching operation is completed, the processor 220 may output the data (DATA) from the second port 232 to the second antenna 290 and may transmit the data (DATA) to the network 298 via the second antenna 290.
